It was attached to my first mail.  I'll attach it here again as po.el,
plus this check:

    (file-exists-p (car (cdr arg-list)))

I also attach file-4.1.5.hu.po; loading this Hungarian file will set
the coding system to iso-8859-2/latin-2:

    emacs --no-site-file -q -l po.el file-4.1.5.hu.po

Now you can edit and save the file.  Starting with a non-existing file
emacs will produce an error message when you will try to save it:

    emacs --no-site-file -q -l po.el not-there.hu.po

Enter:

    # a comment line
    C-x C-s
    error--> and: Wrong type argument: stringp, 1

This used to work with Emacs 20.  As I said: I don't understand
`po-find-file-coding-system'; maybe it's worth to re-write it from
scratch.
